SCN8A is a gene that encodes for a sodium channel in the brain, specifically in the neurons. Mutations in the SCN8A gene have been associated with various neurological disorders, including epileptic encephalopathy and intellectual disability. Research in this area focuses on understanding how mutations in the SCN8A gene lead to these neurological conditions, as well as potential treatment options for individuals with SCN8A-related disorders. Additionally, studies are investigating the role of SCN8A in normal brain function and development.
